Title: Improvements in razors
IPC: B26B21/32
Filed: 1932-03-24
Abstract: 387,166. Safety razors. SEGAL FOUNDERS CORPORATION, 270, Broadway, New York, U.S.A. March 24, 1932, No. 8767. Convention date, June 11, 1931. [Class 30.] The clamping- plate 10 of a safety razor is pivotally carried on a stem 16 slidable in a handle sleeve 14 integral with the guard 11 and is shifted into an extended position, Fig. 2, wherein the slotted blade 32 can be passed over it, by rotation of a knurled end-knob 23 secured to a tube 18 having a helical slot 20 in which rides a spring-pressed pin 17 carried by the stem 16 and guided either in a slot 21 in a rolled-up tube 19 fixed in the handle sleeve by an integral pin 22, or in a similar groove in the handle sleeve itself. The upper part 26 of the guide slot 21 is inclined so that the clamping-plate is also initially turned about the axis of the stem, its edges riding over the bevelled sides of a blade-locating rib 12 on the guard. The clamping-plate is unbalanced to cause it to tilt automatically into the position shown in Fig. 2. Either the sleeve 14 or the stem 16 has a groove 31 accommodating grease or an oil-impregnated felt washer. The rib-accommodating recess 30 in the clamping-plate is extended at 29 to its ends so that the plate may lie nearer to the guard. The transversely flexed blades may be single- or double-edged with cut-away corners and the guard may be toothed on one or both sides. Single-edged blades, when used, are of less than normal width and unsymmetrical longitudinally. A washer 25 spaces the tube-engaging shank 24 of the knob 23 from the sleeve 14. The razor head may be inclined to the handle.
Patent GB-937437-A (GB)
Title: Safety apparatus for the automatic cut-out of tractor engines
IPC: F02D17/04
Filed: 1960-03-11
Abstract: 937,437. Engine stop-gear. H. N. FAULL. March 11, 1960 [March 13, 1959], No. 8772/60. Class 122 (4). [Also in Group XXXI] An automatic device for cutting out a tractor engine when the tractor becomes dangerously inclined comprises an actuator 3 urged to effect cut-out of the fuel supply or electrical system of the tractor engine but normally restrained from such operation, and electrical means for freeing the actuator for operation including a gravity.operated switch 16, movablecore solenoid 18 and electrical contact switch 22 which are so arranged that, when the tractor is dangerously inclined, the switch 16 energizes the solenoid to free the actuator for operation and the switch 22 de-energizes the solenoid so as to necessitate the use of manually-operable means for resetting the actuator for further operation. The actuator 3 is constituted by a cam which is normally locked against rotation by a detent 14 engaging a recess in the cam. The detent is controlled by the solenoid 18 which, when energized by the closing of the adjustable mercury switch 16 upon dangerous tilting of the tractor, acts to disengage the detent and so free the cam for rotation by a spring 12. Means connected with a lever on the cam shaft then acts to cut out the fuel supply to the engine, and the face 4 of the cam opens the switch 22 to break the ignition circuit of the engine and de-energize the solenoid whereby a spring 21 returns the detent 14 to its normal position. Upon return of the tractor to a safe position, the mercury switch opens and the cam shaft may be rotated manually to its normal position by means connected to the lever on the shaft. The engine can be stopped at will by actuating a manual push-button cut-out switch 34. A warning light may be included in the circuit and arranged to be extinguished when the tractor reaches a dangerous angle. In an alternative form, the actuator 3 may be in the form of a body slidable on a guide rod and having a check plate for engagement with the movable detent, a contact plate to operate the switch 22 and a coiled spring which is disposed around the guide rod and reacts against the check plate to urge the actuator to open the switch 22 and cut off the fuel supply. The device may be constructed exclusively for use with internal combustion engines, in which case the switch 22 is situated as described above in the coil ignition circuit or exclusively for use with diesel engines in which case the actuator is connected to the fuel supply.

Title: Improvements relating to motor control systems and circuits particularly for positional and velocity control
IPC: G05D3/12
Filed: 1945-04-09
Abstract: 619,041. Electric control systems. SPERRY GYROSCOPE CO., Inc. April 9, 1945, Nos. 8794, 8795 and 8796. Convention dates, April 8, 1944, April 29, 1944, and May 24, 1944. [Class 40 (i)] [Also in Group XL (c)] In a balanced amplifier forming part of a correspondence control system, signals proportional to the error and derivatives thereof, and transmitter or receiver velocity are combined in the amplifier by applying them respectively to the cathodes and grids of a pair of valves joining one stage of the amplifier. Fig. 1 shows a resultant field type correspondence control system in which positional disagreement between members 12 and 13 causes a signal to be applied to balanced demodulator valves 26 and 27, having byepass capacitors 55 and 56 in their cathode circuits' of such value that a first derivative component is introduced into the resultant differentially varying currents flowing through resistors 53 and 54. These resistors also form the cathode resistors of cathode input valves 61 and 62 which drive output valves 101 and 102 actuating follow-up motor 96 by differentially varying the excitation of the coils 87 and 88 of constantly driven generator 93 connected to the motor. Feedback proportional to the rate of correction is obtained by applying the armature voltage of the motor 96 to the grids of valves 61 and 62 through resistance capacitance differentiating network 112, 113, 75, 76. The arrangement being such that the valves are operated on the linear part of their mutual conductance characteristics. In the modification of Fig. 3 an error integral component is introduced by connecting a resistance capacitance integrating network 61-65 across the demodulator output. To match the high output impedance of this network to the low input impedance cathode input valves 76, 77, cathode follower valves 71 and 72 are interposed. The valves 93 and 94 are suitably biassed by returning grid resistors 105 and 106 to the junction of resistors 97 and 98 connected to corresponding junctions of resistors 81, 82 and 84, 85. In this modification the rate of correction feedback voltage is obtained from an auxiliary generator 141 which may be of the permanent magnet type. In another modification of the arrangement of Fig. 1 (Fig. 4, not shown), the cathodes of valves 61 and 62 are connected to earth through resistors which are high compared with resistors 53 and 54. In this way an auxiliary bias source is unnecessary and phase changes in anode current due, for example, to H.T. variations are minimized by the degenerative feedback across the high resistors, while the degeneration of the rate of correction voltage is no greater than in the arrangement of Fig. 1.
